I'm looking to build a custom optical disc duplicator unit. It appears to be stupid-easy so far except the power connection.

I've found how to hotwire a power supply, but then that requires use of the master power switch on the PSU itself. I'll do that if I have to, but I would rather be able to use the power button on the front of the case.

Since there is no motherboard (it's just the duplicator controller, the psu, and the drives), how does one wire the PSU to use the power switch on the front of the case? The duplicator controller only has a SATA power connection; there is no connector for the main 24-pin ATX cable.

I was hoping to find some sort of PSU switch controller but I'm not finding what I need.

How do either of these work with the switch on the front of the case? It's not a dial-type that would work with the Arduino insctructable, and it's not a toggle.

And further on the point of the toggle, as I mentioned I've found how to hotwire the power supply (I actually also found that same instructable Paragraph with the green and black lead) and that would require my using the master power switch on the PSU itself for on/off function. The toggle switch idea is the same basis but with an additional switch that would have to be mounted somewhere which at that point it would be better to just not bother with a toggle and just use the PSU master switch.

I'm thinking something like this. A control board or something that can utilize the ATX switch on the case, but I don't know if this would work correctly, or if it has some special quirk that makes it for a SuperMicro system only.
